Improvement in tramway-saddles



UNITED STATES PATENT OEEIGE JOSHUA CLAYTON ROBINSON, OF HAMILTON, NEVADA.

IMPROVEMENT IN TRAMWAV-SADDLES.

To all whom 'it may concern.:

Be it known that I, JOSHUA CLAYTON ROBIN- SON, of Hamilton, White Pine county and State of Nevada,have invented certain Improvements Ain a Tramway-Saddle, of which the following is ,a specification:

My invention consists in combining hinged levers with jaws attached to them, and with pulleys working on the levers, for the purpose of a saddle Ato work on a tramway, so that when a weight is put onit holds the saddle tightly clasped on the cable, and when the weight is taken Oi', by means of pulleys working on the levers, the saddle is opened and freed from the cable.

Figure l is an end elevation of the saddle when suspended upon the cable. Fig. 2 is an end elevation when freed from the cable by the weight resting on the pulleys. Fig. 3 is an elevation of a side view of Fig. l.

A, Figs. l and 2, is the frame ofthe saddle. B, Figs. l and 2, is the lower part of the frame that is turned up so as to form a hook, to which the load is attached. C, Fig. 1, is a section of the cable. D D, Figs. l and 2, are levers, which are hinged together. E, Figs. 1 and 2,is the hinge. F F, Fig. l, are the jaws oi' the saddle clasping the cable. Gr G, Figs. l and 2, are pulleys working on the levers D D, by which the weight is,

' taken o' of the cable by the pulleys running upon a track, which is placed wherever it is desirable to free the saddle from the cable. F F, Fig. 2, shows the jaws of the saddle relieved from the cable. Gr G, Fig. 2, shows the pulleys in the position that they are when resting on the track and taking the weight from the cable. A, Fig. 3, shows the frame. O O, Fig. 3, is the cable, a section of which is shown, C, Fig. l. G, Fig. 3, is the side of the pulley G, Fig. l. F F, Fig. 3, is the side of the jaws F, Fig. 1. H, Fig. 3, shows a slot, in which the end of the lever works upward and downward when the jaws of the saddle are opened or closed.

Now, it will be seen, by suspending the saddle upon the cable, as shown in Fig. 1, the greater the weight hung on the hook at B the tighter the jaws clasp the cable. It will also be Seen that, when the weight is taken off from the cable and resting on the pulleys, the jaws are opened, as Shown in Fig. 2, and freed from the cable; and, when leaving the track, the weight comes on the cable, the jaws are closed, as shown in Fig. l.

The jaws may be lined with metal, leather, rubber, or wood, as may answer the best purpose.

I claim as my invention- The combination of the hinged levers D D with the jaws F F and pulleys G Gr; also, the head of the frame A from the dotted line upward, substantially as and for the purpose h'ereinbefore set forth.
